PHYSICS: Great job on the problems so far!! Here’s our look how kinetic and potential energy get involved – dart in the block of wood and the bird on the swing. This cute little bird isn’t on a swing, but he is one I came beak to nose with on a mission trip to Costa Rica!
What about even more practical applications? Hmmmm…..
HON CHEMISTRY: Moving right along with the 17 types of chemical reactions, here are the single replacement reactions – and you also got a head start on the activity series!
This makes 15 reactions so far, and we’ll do the rest tomorrow. Careful though, memorize, but don’t just memorize them. Make sure you can apply them as well. When you start to work any equation, first determine what type of reaction it is, then figure out what rule applies and follow it to determine the products. I believe in you! You can do it!!

CHEMISTRY: So, would you like to be Greg on CSI? Great work with empirical formulas today!
The hardest part is that it’s not a set formula for you to plug and play, but if you’ll keep in mind that you’re really just looking for subscripts which are just moles, you’ll be able to think it through. Percent to mass, mass to moles, moles to smallest whole number ratio.
HOMEWORK UPDATE: Omit #38 & 39 for now.
Let’s crank it up a notch tomorrow! 🙂
